This made the same content as before that caused problems:


module myservice_policy 1.0;

require {
     type dovecot_t;
     type mysqld_etc_t;
     type mysqld_t;
     class unix_stream_socket connectto;
     class file { getattr open read };
     class dir read;
}

#============= dovecot_t ==============
allow dovecot_t mysqld_etc_t:dir read;
allow dovecot_t mysqld_etc_t:file { getattr open read };

#!!!! The file '/var/lib/mysql/mysql.sock' is mislabeled on your system.
#!!!! Fix with $ restorecon -R -v /var/lib/mysql/mysql.sock
#!!!! This avc can be allowed using the boolean 
'daemons_enable_cluster_mode'
allow dovecot_t mysqld_t:unix_stream_socket connectto;

What do these 3 comments mean?  I don't think I want to restorecon for a 
socket:

# ls -Z /var/lib/mysql
-rw-rw----. mysql mysql system_u:object_r:mysqld_db_t:s0 aria_log.00000001
-rw-rw----. mysql mysql system_u:object_r:mysqld_db_t:s0 aria_log_control

What does the 3rd comment mean?
